Been in a relationship with this girl for about 2 years and recently she told me that she wanted to break up with me. The reason being, I didn't make her feel super special or happy as per her claims. Prior to break up, everything was good apart from a couple of heated up conversations(very rare actually) wherein I got irritated at her. In her words, we had this awesome chemistry(both physical and mental), perfect for each other and everything was so ****ing good barring the distance between us(long distance relationship). We were so close and attached as much as we couldn't pass a single day without talking to each other. Even the day before the break up she called me up and said she loves me so much and stuff, and the very next day when I called her, BAM!, she broke the ice.
All of a sudden she has become this cold heart-ed girl and started talking to me rudely in order to not let me convince her to get back. Tried calling her up, but she wouldn't answer my calls. Wrote her a letter saying sorry but she was like "very nicely written but it's over". For now, I have decided not to bombard her with calls, texts and come up like a desperate and needy guy. I'm puzzled because she used to love me way more than I used to. It's like I have lost all of my charm and confused on how to make my next move. Any ideas on how to make her convince and get her back?
P.S. Move on is not an answer I'm looking for, because it's never an option in the first place.
